Planning a future with someone you love is one of life's most exciting chapters. But love alone does not protect your finances, your property, or your children if things ever change. A prenuptial agreement, postnuptial agreement, or cohabitation agreement can give you and your partner a clear, written plan for what happens to your assets and responsibilities — no matter what the future holds. Understanding which agreement fits your situation is a smart first step, and you do not have to figure it out alone.

What Is a Prenuptial Agreement and Who Needs One
A prenuptial agreement — often called a "prenup" — is a legal contract signed by two people before they get married. It spells out how assets, debts, and property will be handled if the marriage ever ends in divorce or if one spouse passes away.
Many people think prenups are only for the very wealthy, but that is a common myth. A prenuptial agreement can benefit anyone who owns a home, runs a business, has children from a previous relationship, carries significant debt, or simply wants financial clarity going into a marriage.
Signing a prenup does not mean you expect your marriage to fail. It means you and your partner are starting your life together with honesty, open communication, and a shared plan.
What a Prenuptial Agreement Can and Cannot Cover
A prenuptial agreement is a flexible tool, but it does have limits. Knowing what it can address — and what it cannot — helps you set realistic expectations.
Here are some things a prenuptial agreement can typically cover:
- How property you owned before the marriage will be treated if you divorce
- How debts brought into the marriage will be divided
- Whether one spouse will receive alimony (financial support after divorce) and in what amount
- How a family business or inheritance will be protected
- Financial rights and responsibilities during the marriage
It is important to know what a prenup cannot do. A prenuptial agreement cannot include decisions about child custody or child support — Michigan courts always make those decisions based on what is best for the child at the time of a divorce. A prenup also cannot include anything that is illegal or that punishes one spouse for filing for divorce.
Having a clear understanding of these boundaries helps you and your partner create an agreement that will hold up in court.
What Is a Postnuptial Agreement and When Does It Make Sense
A postnuptial agreement — or "postnup" — is very similar to a prenup, but it is signed after you are already married. The content is largely the same: it outlines how assets and debts would be divided if the marriage were to end.
Life changes after marriage, and a postnuptial agreement can help couples adjust their financial plans to match. A postnup may make sense in several situations:
- One spouse starts a new business and wants to keep it separate from marital assets
- A spouse receives a large inheritance and wants to protect it
- The couple is going through a rough patch and wants to formally define financial expectations before deciding whether to continue the marriage
- A couple simply forgot to create a prenup and wants to address finances now
A postnuptial agreement can also help rebuild trust between spouses after a financial disagreement. Putting financial expectations in writing can bring a sense of stability and calm during uncertain times.
What Is a Cohabitation Agreement and Why It Matters
A cohabitation agreement is a legal contract for couples who live together but are not married. In Michigan, unmarried partners do not have the same automatic legal rights that married couples do. If you share a home, a bank account, or major expenses with a partner and things do not work out, there may be no legal framework to protect you — unless you have a written agreement.
A cohabitation agreement can cover important areas such as:
- Who owns what property and in what percentage
- How shared living expenses are split
- What happens to a jointly purchased home if the relationship ends
- How shared debts will be handled
- Financial support arrangements between partners
Without this agreement, disputes over shared property can become complicated, costly, and emotionally draining. A cohabitation agreement gives both partners clear expectations and legal protection, whether the relationship continues or not.
How These Agreements Are Different from Each Other
While prenuptial agreements, postnuptial agreements, and cohabitation agreements serve similar purposes, each one applies to a different life situation. A prenuptial agreement is for couples planning to marry. A postnuptial agreement is for couples who are already married. A cohabitation agreement is for couples who live together without getting married.
All three agreements require both partners to be honest about their finances and to sign the document willingly. Courts will look closely at whether both parties had a chance to review the document and whether anyone signed it under pressure. Working with a family law attorney helps make sure the agreement is written fairly and will be recognized by a judge if it ever needs to be.
Common Mistakes to Avoid When Creating These Agreements
Even a well-intentioned agreement can be thrown out by a court if it is not done properly. One of the most common mistakes is waiting until the last minute — signing a prenup the night before a wedding, for example, can make it look like one partner was pressured. Courts want to see that both people had plenty of time to read, review, and think about the agreement.
Another mistake is leaving out important financial information. Both partners must fully disclose what they own and what they owe. If one partner hides assets, the agreement can be canceled entirely. Each partner should also have their own attorney review the document to make sure their interests are fairly represented.
How Michigan Law Affects These Agreements
Michigan courts will enforce a prenuptial agreement, postnuptial agreement, or cohabitation agreement as long as it meets certain standards. The agreement must be in writing, signed by both parties, and entered into without fraud or pressure. It must also not be so one-sided that it shocks the conscience of the court.
Michigan law does not require both parties to have separate attorneys, but it is strongly recommended. Having independent legal advice shows the court that both people understood what they were signing. It also reduces the risk that an agreement will be challenged later.
Every couple's situation is unique, and what works well for one pair may not be right for another. That is why personalized legal guidance matters so much when drafting these documents.
