Is a void contract enforceable in court?

If you have an agreement in place, you can simply follow what the agreement says you need to do in order to exit. If you don't, you would need to negotiate an exist with the other party/parties that are involved to ensure a smooth and amicable exit. I can assist you with that.

The answer to your question is, as so many answers in the legal world..."it depends." It depends because it is possible that the company could have included in the original contract with you a clause preserving its right to change its policy without notice (although it could be argued that such a clause is unenforceable in a court) or it original contract may include language in which you waive your right to notice or some other similar waiver. The contract you are referring to in your question would need to be reviewed by an attorney practiced in contract law.

Generally, the answer to your question is "yes, a company can restrict employee's personal use of a company-owed device" as the company's have the right to restrict access, use of their own property and further, they have a right to protect proprietary property that may be affected by the personal use of a device which the company owns. Another question that your question raises, is, does a company actually achieve the restriction of its company-owned device in its Acceptable Use Policy. The policy itself needs to be examined by an attorney highly familiar with contract drafting, revision, etc.

The issue does not appear to be what provisions should be included but instead what contracts should be included. Based upon your needs as detailed above, you would start with the formation documents for the entity, then include employment agreements for the parties. The issues that you are concerned about are probably best resolved with this type of contract structure.

Not sure that the non-compete is the right agreement for this scenario. You might want to consider an NCND agreement. This is a Non-Circumvent Non-Disclosure Agreement. Without knowing more about the relationship between the parties, I would look first to this type of document.
