Estate planning is about more than just planning for the future. Depending on your situation, there are financial vehicles that can provide significant savings and protections now as well.
A revocable living trust won't protect you against creditors or give you any tax benefits, but it will make the transfer of property much smoother after death and can be changed at any time. Irrevocable trusts, on the other hand, provide not only protection against creditors and tax benefits, including an asset protection trust, but can also contribute to your legacy.
