Costs of Prenuptial Agreements in California

The cost of prenuptial agreements in California can vary depending on whether you are drafting or reviewing an agreement.

• Drafting Costs: Hiring a lawyer to draft a prenuptial agreement typically incurs a flat fee. According to ContractsCounsel's marketplace data, the average cost for drafting a prenup in California is around $980.00. The fee includes time spent recording assets, drafting the agreement, and any necessary revisions.
• Reviewing Costs: If you need a lawyer to review an existing prenuptial agreement, the average flat fee is about $550.00 in California. This fee covers the lawyer’s time spent reviewing the agreement, explaining the terms to the client, and ensuring the client’s rights are protected.

Hourly Rates for Prenups

An hourly rate fee structure is one of the more popular arrangements for hiring a family law attorney in California. When using an hourly rate structure, the attorney will bill the client at a set hourly rate for the number of hours worked on the project.

Billable hours can include:

• Meeting with the client to discuss the content of the prenup
• Time spent drafting
• Revisions
• Being present when the agreement is signed

The marketplace data for ContractsCounsel shows that the average hourly rate for a family lawyer in California ranges from $200 - $350 per hour.

Flat Fees for Prenups

Flat rate billing structures are becoming more common for contract drafting projects. When using a flat fee rate, a lawyer will provide the client with a quote for the entire job. If the client agrees, they will pay upfront, and the lawyer will begin working on their case or project.

Clients usually prefer flat fee rates because they know their total bill before agreeing to legal services. In addition, lawyers benefit from this fee structure because they collect payment upfront and don’t have to keep track of their billable hours.

ContractsCounsel's marketplace data shows the average flat fee rate for a prenuptial agreement in California is $700.00.

Factors Affecting the Cost of Prenuptial Agreements

The cost of a prenuptial agreement in California can vary widely depending on several factors. Understanding these variables can help couples anticipate expenses and choose the best legal support for their needs.

• Complexity of the Agreement: The more complex the agreement, the higher the cost. If a couple has significant assets, business interests, or complex financial arrangements, the lawyer will need to spend more time drafting a comprehensive agreement that addresses all contingencies. This might include provisions for property division, spousal support, and inheritance, all of which require precise legal language.
• Number of Assets and Debts: Couples with numerous assets, investments, or properties will likely pay more for a prenuptial agreement. Lawyers must carefully document and include each asset to ensure proper division in case of divorce. The same applies to debts; detailing these accurately and determining responsibility can add to the time and cost involved.
• Disputes or Disagreements: If the couple has disagreements or disputes over the terms of the prenuptial agreement, this can increase legal fees. In these cases, the lawyer may need to engage in negotiations or revisions, requiring more time and potentially involving mediation services.
• Lawyer’s Experience: The experience level of the lawyer also plays a role in cost. Attorneys with more experience in family law, especially those specializing in prenuptial agreements, often charge higher fees. However, working with an experienced lawyer can provide peace of mind, knowing the agreement is legally sound and less likely to be contested in the future.

What is a Prenuptial Agreement?

A prenuptial agreement, commonly shortened to “prenup,” is a legally binding contract executed by couples before marriage. A prenup is a helpful planning tool for couples because it documents each person's assets and debts before the marriage and acts as a settlement agreement if the couple divorces.

Suppose a couple marries without a prenup in place. Then, if they ever get divorced, they will be subject to their state’s divorce laws for property division.

California is a "community property" state. This means that any assets or debts acquired during the marriage are owned equally by both spouses, regardless of who earned the money or whose name is on the account. Property each person owned before the marriage remains their separate property. In a divorce, California law requires that all community property be split equally.

One criticism of community property laws is that they tend to favor the spouse in the marriage who earns less. Even if one spouse contributes zero money during the marriage, they will still end up with half the assets in a divorce.

To avoid this automatic property division, couples can use a prenuptial agreement to dictate how they want their assets to be divided in a divorce. A prenuptial agreement must be adequately drafted, so it is common for couples to hire an attorney for help. A lawyer will know how to draft a contract that protects both parties and is legally enforceable under California laws.

What's Typically Included in a California Prenuptial Agreement

In California, prenuptial agreements are governed by the state's version of the Uniform Premarital Agreement Act (UPAA), which includes stricter requirements than most states, so every prenup must adhere to these laws.

• Premarital assets. A list of each person's assets before entering the marriage and how the assets will be treated after the marriage.
• Premarital debts. A list of each person’s debts before the marriage and who will be responsible for the debts after the wedding.
• Marital assets. California considers any property gained during the marriage equally owned by both spouses. However, a prenup can override this law and dictate that certain assets remain the sole property of one spouse.
• Marital debts. Like assets, in California debts acquired during the marriage will be both spouses’ responsibility. Prenups can be used to split up any marital debt.
• Right to alimony. The couple can agree whether one spouse will pay alimony to the other. In California, a spousal support waiver is only enforceable if the person giving it up had their own lawyer, and courts can still refuse to enforce it if it would be grossly unfair at the time of divorce.
• Distribution of property. How property will be divided in a divorce.
• Inheritance. Suppose either spouse has children from a previous marriage. In that case, the prenup can dictate what assets will go to the children if their parent dies.

One important limit: a prenup cannot restrict child support in California. Child support belongs to the child, and courts will not enforce any provision that tries to waive or cap it.

In addition to these clauses, California prenups are unique because they allow couples to include information about the rights, roles, and responsibilities of each partner in the marriage if the terms do not violate public policy. Some examples of roles and responsibilities can include:

• Who is expected to pay specific bills
• How tax returns are filed
• How bank accounts are handled
• Rules for large purchases

To be legally enforceable, prenuptial agreements must be made voluntarily with one’s free will and signed by both parties.

How Long Before the Wedding Do You Need a Prenup in California?

California law requires at least 7 calendar days between when a party is first presented with the final version of the prenup and when they sign it. If the agreement is signed sooner, it is not enforceable. This waiting period applies each time material changes are made, so last-minute revisions can restart the clock.

In practice, you should start much earlier than 7 days out. Between hiring lawyers, exchanging financial disclosures, negotiating terms, and allowing revision time, most couples need 1 to 3 months to get a prenup done properly. Starting close to the wedding date also invites a later argument that the agreement was signed under pressure, which is one of the most common grounds for challenging a prenup.

What Makes a Prenup Unenforceable in California?

A California prenup can be thrown out if it wasn't signed correctly, wasn't fair when signed, or wasn't based on honest disclosure. These are the most common reasons courts refuse to enforce a prenuptial agreement:

• Signed less than 7 days after receiving the final agreement (the waiting period is mandatory, and missing it invalidates the agreement)
• No independent lawyer and no valid waiver (a party without counsel must sign a separate written waiver after being advised in writing to get a lawyer)
• Incomplete financial disclosure (hiding or misstating assets, debts, or income gives the other party grounds to challenge the whole agreement)
• Signs of pressure or coercion (presenting the prenup days before the wedding, or making the wedding conditional on signing on the spot)
• Unconscionable terms (provisions so one-sided that a court finds them fundamentally unfair, judged both when signed and, for spousal support, when enforced)
• Terms that violate public policy (waiving or capping child support, or provisions that penalize a spouse for filing for divorce)

Most of these problems are avoidable with proper process: start early, disclose everything, and make sure each party has their own lawyer. This is the main reason working with an experienced California family lawyer matters more than the drafting itself.

Benefits of a Prenuptial Agreement

Prenuptial agreements offer significant benefits beyond simply protecting assets in the event of a divorce. These agreements can play a crucial role in setting clear expectations and fostering open communication between partners, ultimately strengthening the marriage.

• Asset Protection : One of the primary benefits of a prenuptial agreement is the protection it provides for individual assets. Couples can outline what is considered separate property and ensure that it remains protected if the marriage ends. This is particularly important for individuals entering a marriage with substantial assets, businesses, or real estate properties. A prenup offers clarity and safeguards those assets from being divided or claimed by the other spouse.
• Debt Protection: Just as a prenuptial agreement can shield assets, it can also protect against debt. If one partner has significant debt, such as student loans or credit card debt, a prenup can specify that the other partner will not be responsible for these liabilities in the event of a divorce. This can provide peace of mind and financial security, ensuring that one spouse’s financial decisions don’t impact the other.
• Customizing Financial Arrangements: Prenuptial agreements allow couples to create a tailored plan for managing finances, property division, and spousal support. Rather than relying on California’s community property laws, which may not suit every couple’s situation, a prenup lets partners determine how assets, debts, and other financial matters will be handled. This customization can lead to more equitable and fair outcomes for both parties.
• Strengthening the Marriage: Many people overlook the potential positive impact a prenuptial agreement can have on a relationship. By discussing financial matters and expectations openly before marriage, couples can build a foundation of trust and transparency. A prenup encourages honest conversations about important topics such as financial goals, spending habits, and long-term planning. Establishing these agreements early can reduce potential conflicts later on, as both partners have a clear understanding of each other’s expectations.
• Ensuring Family and Inheritance Protection: For couples with children from previous relationships, a prenuptial agreement is especially beneficial. It allows individuals to outline how assets and inheritance will be distributed to children from prior marriages. This not only protects those children’s inheritance rights but also reduces potential disputes among family members. In the unfortunate event of a spouse’s death, a well-drafted prenup can ensure that assets are distributed according to their wishes.
• Reducing Conflict and Simplifying Divorce: In the event that a couple does decide to divorce, having a prenuptial agreement in place can reduce conflict and streamline the process. The prenup serves as a guideline for how assets and debts should be divided, which can eliminate lengthy court battles and negotiations. This can save both time and legal expenses, providing a less stressful transition for both parties.

Prenuptial Agreement Services

California does not strictly require both parties to hire lawyers, but a prenup signed without independent counsel is much easier to challenge later, and a spousal support waiver is only enforceable if the party giving it up had their own lawyer. In practice, most California couples each hire their own attorney. Lawyers offer two main services when it comes to prenups: drafting a new agreement and reviewing an existing one.

• Drafting a New Prenuptial Agreement: When drafting a prenuptial agreement, the lawyer will work closely with the couple to document their assets, debts, and terms for property division. The attorney ensures the contract is comprehensive, legally enforceable under California laws, and reflects both parties' wishes.
• Reviewing an Existing Prenup: If one party already has a prenup drafted, the other spouse should hire their own lawyer to review it. The reviewing attorney will evaluate the agreement to ensure it aligns with their client’s best interests and that the client fully understands the terms before signing. This independent review makes the agreement much harder to challenge later.

Who Pays for a Prenuptial Agreement?

Legal fees for prenups are paid by the individuals within the couple that plan to get married. Each is responsible for their own fees, but may choose to use a joint account to pay for the work.

In California, each person should have their own independent lawyer, both to protect their interests and because some terms, like spousal support waivers, are only enforceable if the waiving party had counsel. So each member of the couple will typically pay their own legal fees.

There may be certain situations where parents of the engaged couple insist they put a prenup in place (potentially because of inheritance reasons), so they may end up paying the legal fees associated with the prenup.

Tips for Hiring a Prenuptial Agreement Lawyer

Finding the right lawyer to draft or review a prenuptial agreement is crucial. Here are some practical tips to help you choose the best professional for your needs:

• Check Credentials and Licensing: Ensure the lawyer is licensed to practice family law in California and has a good standing with the California State Bar. This guarantees they are qualified and adhere to ethical standards.
• Look for Specialization in Family Law: Choose an attorney who specializes in family law, particularly in prenuptial agreements. Lawyers with specific experience in this area are more likely to be familiar with California’s prenuptial laws and can provide a more effective, legally sound agreement.
• Compare Rates and Fee Structures: Ask about the lawyer’s fees upfront and whether they offer flat fees or hourly rates for prenuptial agreements. Comparing rates from different lawyers can help you find a service that fits your budget without compromising on quality.
• Ask About Experience with Prenups: It’s important to know if the lawyer has handled prenuptial agreements similar to yours. Ask about their experience drafting prenups for clients with similar financial situations or family dynamics, such as business ownership, high-value assets, or blended families.
• Request Client Testimonials or References: A reputable lawyer should be able to provide testimonials or references from past clients. Hearing about other clients' experiences can give you confidence in the lawyer’s ability to handle your case effectively.
• Discuss Availability and Communication: Make sure the lawyer is accessible and responsive. Prenuptial agreements often require multiple discussions and revisions, so it’s essential to work with someone who is available to address questions and provide updates.

How To Get a Prenup in California

Getting a prenuptial agreement will involve finding and hiring a family law lawyer that has a deep understanding of the laws in California to make sure the couple is legally protected. The different ways you can find a lawyer are:

• Post a project on a legal marketplace, like ContractsCounsel, to get quotes from lawyers to handle the project.
• Find lawyers by Googling them online and making inquiries into their offices.
• Go to the California State Bar website to find lawyers and make inquiries.
• Ask for referrals within your personal network to a family law lawyer.

Online templates are widely available, but they are risky in California. The state's enforceability rules are strict, and key protections like spousal support waivers only hold up if each party had independent counsel. Most lawyers also find templates inadequate and spend more time fixing them than working from their own baseline.

If you want to find a quick way to get quotes from vetted California family law lawyers, post a project on ContractsCounsel’s marketplace. You can expect to receive multiple quotes from lawyers in our network on a flat fee basis and be able to speak to them before hiring.
