Check with the attorney as some do not like to update a will or trust another attorney initiated.
We are in the middle of settling my dad's estate who had a will and a living trust. If there is a living trust all accounts have to be retitled into the name of the trust as well as all physical property and vehicles. IRA's, 401K's, employee stock plans and life insurance should have beneficiaries. With all that being said we are still going to probate as my dad had an employee stock plan that did not have a beneficiary, but because of the funds in the account we are going to probate and more than likely have to pay over 10K to get my mother her money. We double checked everything and God forbid if mom passes everything is taken care of.
Living trusts should be updated every 5 years per our attorney. I also found out that if you list your minor children as beneficiaries on your accounts you should appoint a custodian for the kids to manage the money in case you pass.
