Is a prenuptial agreement legally binding?
I am planning to get married and I have been advised to consider a prenuptial agreement to protect my assets in the event of a divorce. However, I am unclear on the legal validity and enforceability of a prenuptial agreement and whether it can be challenged or overturned in court. Therefore, I would like to seek the advice of a lawyer to help me understand the legal implications of a prenuptial agreement and ensure that my interests are protected.
Briana C.
Judges in most cases honor and enforce (signed and notarized) prenuptial agreements between two spouses as long as both parties entered it freely and voluntarily and with full knowledge of one another financial circumstances, and the agreement is not "unconscionable." A prenuptial agreement may not be enforced if (1) either party signed it under duress or coercion or undue pressure (or, say, the night before the wedding), (2) the party seeking to enforce it did not truthfully and completely disclose their financial information, or (3) enforcing the prenup would leave one spouse so destitute that they could not meet their most basic living expenses (i.e., would be forced onto welfare). In short, the prenuptial agreement will be enforced if (1) all the procedural requirements were met at the time it was signed and (2) the terms are not unconscionable, taking into account the circumstances existing at the time of divorce.

How does a prenuptial agreement affect estate planning?
I am getting married soon and I am interested in understanding how a prenuptial agreement would affect my estate planning. I would like to know what steps I should take to ensure that my assets are protected and that my wishes are carried out after I pass away. I am also curious as to how a prenuptial agreement might affect the distribution of my assets to my family members and other beneficiaries.
Briana C.
A prenuptial agreement does not create an estate plan. But it can do two things. First, a prenuptial agreement can create a contractual promise on the part of one or both spouses to do something in particular with their estate plan (such as promising to leave the marital home to the surviving spouse, or promising to leave everything they have to the surviving spouse, or promising to set up a trust, etc. etc.). If this contractual promise is broken, the surviving spouse has a contract claim against the estate of the dead spouse. Second, and almost the opposite, in a prenuptial agreement one or both spouses can waive the rights they would otherwise have by statute, thus freeing up the other spouse to do whatever he or she wants with her estate plan. Without a prenuptial agreement, a surviving spouse is entitled by statute to inherit a certain proportion of the estate of the dead spouse (the exact proportion depends on whether or not the dead spouse has a will, and/or has surviving children). The prenuptial agreement can override these statutory rights and provide that the surviving spouse is not entitled to inherit anything from the dead spouse, except for anything the dead spouse may choose to leave the surviving spouse in his or her will.

Is a prenuptial agreement legally binding in the event of a divorce?
I am engaged and considering getting a prenuptial agreement to protect my assets in case of a divorce, but I have heard conflicting information about their enforceability. I have worked hard to build my business and accumulate significant savings, and I want to ensure that these assets are protected in the event of a divorce. I would like to know if a prenuptial agreement is legally binding and what factors can affect its enforceability in my state.
Khari P.
A prenup would be binding in a divorce action provided that the prenuptial agreement was written properly, both parties disclosed all relevant financial information along with an acknowledgement that they had the right to consult an attorney of their own choosing before signing, and the signing was witnessed by a notary.

How does a prenuptial agreement affect taxes?
As a couple planning to get married, my partner and I are concerned about the tax implications of a prenuptial agreement. We are wondering if entering into a prenuptial agreement will have any impact on our tax obligations or if there are any specific tax considerations that we should be aware of. We are seeking advice from a lawyer who can provide us with guidance on this matter.
Briana C.
A prenuptial agreement does not in itself affect how taxing authorities will treat the spouses. But it can create promises between the spouses toward one another. For example, it may create a promise to file jointly, or specify that they are making no such promise. And it can create a promise by each spouse to pay the other back for any taxes the other pays on his or spouse's behalf. The decision whether to file jointly or separately does have tax implications with taxing authorities.
Quick, user friendly and one of the better ways I've come across to get ahold of lawyers willing to take new clients.
