A postnuptial agreement is defined as any agreement or contract entered into by a married couple following the establishment of a legal marriage. The terms of the postnuptial agreement will seek to mitigate problems in the future of the marriage by answering the questions in the postnuptial agreement. Common terms of postnuptial agreements include items such as financial considerations, childcare, management of investments, changes in lifestyle, and a whole slew of other personal considerations. Having legal counsel present when establishing a postnuptial is essential to ensuring the validity of these documents.
