If there is a trust and I am co-trustee, what do I do?

I assume the trustmaker is now deceased. If they didn't sign a prenuptial agreement, his wife is entitled to all of the community property and 1/3 to 1/2 of all the trusmaker's separate property (depending on how many kids there are). Her rights supersede the trust. In these cases, it's usually best to gather all heirs and beneficiaries and work out a written settlement agreement.
