Generally, Revocable Trusts are probate avoidance tools, allowing assets transferred to the Trust to avoid the probate process on upon the death of the Donor of the Trust.
Irrevocable Trusts, on the other hand, may provide some liability avoidance benefits. But transferring any assets to an Irrevocable Trust forever divests the donor of true ownership interest, so these types of Trusts must be used carefully.
