Pre-nuptial agreements can help distribute an estate according to the party’s wishes, can protect property from creditors, and can protect the interests of children in that property. A post-nuptial agreement is a voluntary contract created after marriage. Post-nuptial agreements can help resolve issues in a marriage by ending disagreements over finances, assets, children and even chores. The agreements can stop conflict and promote harmony. Post-nuptial agreements also can be beneficial if the financial status of either spouse changes, such as through a career change, an inheritance, change in investments or the selling of a business.
