Are there any downsides of a living trust? MN USA

I’m in my 40s. I have a 13 yo.

Divorced.

I own a home with $250k equity. Mortgage $150k.

Pension. IRA.

I’m trying to decide what to do if something were to happen to me. I also don’t want my ex to have access/control of my child’s inheritance.

What are the consequence of retitling my home? Other cons?
