‘Post nups’ are often signed after a prenuptial agreement if a couple is concerned about the strength of their pre nup and want to reaffirm the agreement. For example, the prenuptial agreement may be deemed weak if it was signed mere days before the wedding.
Post nups are also often undertaken when there has been a change in circumstances. For example, one party has had a career change or inherited money. Lastly, postnuptial agreements may be chosen when a couple is experiencing relationship difficulties and wants to move forward with the relationship with financial peace of mind.
