Elliot Polland is a New York divorce attorney with nearly 50 years of experience, so he knows a thing or two about what can make or break a relationship.
Polland spoke with INSIDER right after getting out of court about the biggest mistakes married couples make and the best things married couples should do to make sure their relationships will last.

Set up boundaries with in-laws and other family members.
While Polland said that family members' insights can be useful in noticing things about a person that their partner doesn't see, it's important to make sure they don't take it too far.
"There are many times where I've had clients coming in and saying that their in-laws have destroyed their marriage," he said.
It's ultimately up to the couple to decide what those boundaries should be.
"I don't know that there's any magic formula for that," he said. "Every situation is different."
Maintain an affectionate physical relationship.
It's the little things that go a long way.
"Obviously a sexual one is important, but even for older couples where that becomes less important, even the cuddling and the hugging certainly maintains that close connection that I think is very important for maintaining a relationship," he said.
Keep records of your assets.
"Banks and most other financial institutions don't maintain records beyond six years," he said. "If somebody claims that they came into the marriage with X dollars and tries to claim that that was their separate property if there were a divorce, if they didn't maintain those old records, they would have virtually an impossible task in proving that this was their pre-marital fund."
Polland advised scanning the necessary documents and entrusting them to a parent of sibling.
