sorry for your loss. see a lawyer. we can't see the trust instrument which dictates how the property held by it is treated and what happens to it when one beneficiary dies.
I have never seen one trust where both H&W contribute property to it and they both are beneficiaries. usually, there are two separate trusts where the other spouse and maybe others named as beneficiaries. the only situation where I could see both H&W as beneficiaries is when a third party sets up a trust and names H&W as beneficiaries.
