Like most legal matters, it is strongly advised to work with an experienced and knowledgeable family law attorney to assist you with creating your prenuptial agreement. While it’s both legal and possible to create one without a lawyer involved, it could present many challenges and pitfalls that could impact both parties in the future. A lawyer knows how to properly structure a prenup so it is fair and in your best interest. They can also help identify blind spots and loopholes you want to avoid. Additionally, for a prenup to be legal and binding, it must be placed in writing and signed by both parties.
