When In-Laws Are Hurting Your Marriage: How to Set Boundaries Together

When in-laws are hurting your marriage, the most important relationship to work on is usually the one with your partner, not with their parents. Couples who manage in-law tension well agree on boundaries together, and each partner takes the lead in handling their own family. Problems tend to grow when one partner feels unsupported, caught in the middle, or expected to manage their partner's family alone.

In-law problems are usually solved by the couple, not with the in-laws. Your partner is the bridge to their family.

Common in-law problems

• Unannounced visits or too much involvement.
• Criticism of your parenting, home, or choices.
• Interference in decisions about money, children, or where you live.
• Expectations about holidays and family time.
• A partner who can't say no to their parents.
• Feeling excluded or not accepted by the family.
• Cultural or religious differences in expectations.

Why your partner matters most

You can't control your in-laws' behaviour, and trying to change it directly often creates more conflict. Your partner, however, has a long-standing relationship with their family and is usually better placed to set limits with them. The key question is often not "how do I deal with my mother-in-law?" but "can my partner and I agree on what's okay, and will they support me?"

Talk to your partner first

Choose a calm time and focus on specific situations and how they affect you, not on attacking their family:

"When your mum drops in without calling, I feel like I don't have any privacy in our home. Could we ask her to message first?"

Try to understand your partner's position too. They may feel torn, guilty, or protective of their parents. Many people find it hard to set boundaries with their own family, especially in cultures where family obligations are strong.

Agree on boundaries together

Discuss and agree on specifics:

• How often you visit or host.
• Whether visits need to be planned.
• How decisions about children are made, and that parenting choices are yours.
• How holidays are divided between families.
• What topics are off-limits.

Then present them as a couple: "We've decided…" rather than "My wife wants…"

Each partner handles their own family

A useful general rule is that each partner takes the lead in communicating difficult messages to their own family. It's usually received better from a son or daughter than from a son- or daughter-in-law, and it protects the in-law relationship.

When your partner won't support you

If your partner consistently sides with their family, or refuses to set any boundaries, the issue is in the marriage itself. It may reflect deeper loyalty conflicts or different expectations about family. Couples therapy can help, especially with a therapist who understands your cultural background.

A worked example

After their baby was born, Aisha's mother-in-law visited almost every day and often criticised how she was feeding and holding the baby. Aisha felt exhausted and unsupported. When she talked to her husband, Omar, he admitted he hadn't realised how much it was affecting her; he assumed his mother was helping. They agreed visits would be twice a week, planned in advance, and that parenting decisions were theirs. Omar told his mother himself, kindly but clearly. There was some hurt at first, but within a few weeks the visits felt more relaxed for everyone.

Questions to ask each other

• What does each of us think a healthy relationship with family looks like?
• What expectations did we each grow up with?
• Which situations with family feel hardest right now?
• How can we show each other that we're on the same side?

What to say to in-laws directly

Sometimes you'll need to respond in the moment. Short, polite, and firm usually works best: "Thanks for the suggestion, we've decided to do it this way." Or: "We'd love to see you; can you message before you come over?" You don't need to justify every decision or win the argument. Calm consistency tends to work better over time than a single big confrontation.

Common questions

How do I deal with a mother-in-law who criticises me?

Talk to your partner first and agree on how to respond. Ideally, your partner addresses repeated criticism with their parent. You can also respond calmly yourself: "We've decided to do it this way, thank you."

What if my partner always takes their parents' side?

Explain specifically how it affects you and ask for their support. If they consistently can't support you, couples therapy can help explore the loyalty conflict.

How often should we see the in-laws?

There's no rule. Agree on a frequency that works for both of you, considering family expectations, distance, and your own needs.

Can in-law problems lead to divorce?

They can contribute significantly when a partner feels unsupported over a long time. Couples who face in-law issues as a team usually cope much better.
