You can probably take care of some estate planning tasks without hiring a lawyer. For example, if your situation is simple and you have good do-it-yourself resources, you might make a basic will, finalize health care directives and powers of attorney, or even draft your own living trust to avoid probate court. However, there are many times when an experienced estate planning lawyer can be a big help. (See Ten Ways an Estate Planning Lawyer Can Help You.)
If you have substantial assets, fear family disagreements, or simply feel more confident placing your affairs into the hands of an experienced professional, it makes good sense to hire an estate planning lawyer.
