For most, the answer is probably not. Today you can go into any online/offline stationary store and purchase a living trust template. Then you just need to fill it out, sign, notarize and store it securely. As events happen in your life (asset purchase, child’s birth, marriage, etc) you would open the template and fill out all the details again, including any updates. Then again you would need to sign, notarize and store it securely.
The trust process is trivial for most people as it primarily requires assigning beneficiaries and transferring title of your assets from your individual name to your living trust. For anyone that is seeking legal advice or has an overly complicated estate, an attorney is highly recommended.
