# Adult Children Moving Home: Protecting Your Retirement

Your adult child loses a job, ends a relationship, or needs time to save money. Moving back home feels like the obvious solution. Before you open the door, establish clear financial and personal boundaries or risk derailing your retirement plans.

The first step involves determining who pays for what. Create a written agreement covering rent, utilities, groceries, and household expenses. Some parents charge market rent to reinforce financial responsibility and build a savings fund for their child. Others ask for a smaller contribution or none at all during a crisis. Either way, document the arrangement to avoid resentment and misunderstandings.

Your housing situation matters. If your mortgage is nearly paid off, absorbing an additional adult costs less than for parents still carrying significant debt. Calculate the real expense: utilities, food, property tax increases on a larger utility bill, and potential home repairs triggered by increased wear and tear. Some financial advisors suggest charging rent equal to 30 percent of your adult child's income, a standard used in tenant screening.

Set a move-out timeline immediately. "We can help for six months while you save and find stable employment" creates accountability. Without a deadline, temporary arrangements become permanent, consuming resources needed for your healthcare, long-term care, or travel plans.

Protect your retirement accounts and insurance policies. Your adult child should not become an authorized user on credit cards or accounts unless absolutely necessary. If they co-sign debt or borrow money from you, get it in writing. Family loans often damage relationships when repayment expectations clash with reality.

Consider the tax implications. If your child pays rent, you might claim it as income. Life insurance beneficiary designations should remain unchanged unless you've specifically decided otherwise. Review your estate plan if your child has financial problems. A will leaving assets to someone struggling with debt or addiction may fund poor decisions rather than provide security.
