The only prudent way to plan for probate is to have a thorough assessment of your financial situation and assets by a qualified estate planning attorney or other estate professional.  Self help and do it yourself wills and will kits often create more problems than they solve, and cost multiple times more in the way of estate expenses in the long run than they save in the short run.  Hire a professional and do it right.  The estate that you have worked a lifetime to build is worth investing the relatively small amount of funds needed to get sound legal advice.
