In order to write a will, there are three basic categories of steps: 1. Identify the estate holder, 2. Revoke all previous wills, and 3. write will, detailing all assets, liabilities and beneficiaries. Of course, the details at each step are extremely complicated, as probate law requires everything be documented and explained in great length and detail, in order to avoid confusion and disputes during probate court. Additionally, a professionally written will can avoid the costs of probate court all together.
