As you revoke the trust, you must decide on an appropriate form of ownership for your assets. Right of survivorship arrangements do seem appropriate to your situation. In your letter of instruction to your financial institutions, ask them to place the accounts into your names as joint tenants with rights of survivorship. They will require both of you to sign their contract or signature card. Avoiding probate seems to be an important issue to you.
Probate takes time and costs money.
Often there is a faster, cheaper alternative that works just as well. You should not use rights of survivorship because your estate taxes would be too high. You need a Will to name your heirs. The probate process protects your hard earned assets from bogus claims. It establishes that the document presented as your Will is authentic.
