Hi Jan,
Seek an attorney that does a lot of work in estate planning. As Gary has said we all should have done these things regardless of cancer. Because you have young children you will probably want to spend a fair amount of time with creating a trust for their care. This will involve choosing guardian(s) and how monies will be distributed. Many states will distribute estate proceeds when the child reaches 18, which is far too young an age to deal with a large sum of money.

For my wife and I, getting our wills and trusts set up was a big relief because we new we should have done it long before cancer forced the issue. If you search the financial forum you will find much discussion in the past couple of years.

Our total bill was around $300.00 and well worth it. We are not wealthy but our estate is suprisingly very sizeable. We both have substantial life insurance policies and our investments and retirement funds together with our home amount to a pretty big number. For the tax reasons alone taking care of this will be very worthwhile.

It is VERY OK to survive your cancer and still have this work done.
