Chapter 13 exposes the inheritance to being taken for the creditors for the entire length of the Plan. Five years (there are some circuits which *are* allowing shorter plans, but I'm not keeping track of those exceptions) is a lot longer than six months.
Life insurance proceeds belong to the beneficiary, NOT the BK estate. Mistakes in keeping track of which beneficiaries are still alive can result in the proceeds being dumped back into the Probate Estate (owned by the dead guy after death) and could be claimed by creditors during settlement of the probate/non-probate estate, but otherwise they would not become part of the bankruptcy estate.
A living trust does NOT provide any protection from creditors. By definition, they are not only revocable at whim during your lifetime, they are (and this is the key) for the benefit of the person who created the trust and put funds into it. Same rules for creditors whether BK is filed or not, and all assets of such trusts are assets of the BK estate.
If you are dead-set on asset protection, the techniques are beyond the scope of these questions, but in general they include converting assets into "safe" forms which cannot be executed on such as equity
in the house (However, the homestead exemption is almost criminally small in many states, and is limited for BK purposes to $125,000 anyway.), tax-qualified retirement funds (limits on how much you can put in them each year, unless you have a business structure that allows some rather large annual contributions) which are protected to varying amounts depending on state law, other assets under state law, and sometimes even IRREVOCABLE trusts for your benefit and which you no cannot control (strict rules surround these). Offshore trusts are rarely worth the trouble unless you're talking about millions of dollars in total assets. There is also the question as to whether your state has its own BK exemptions (an "opt-out" state), or if your legislature chose to "opt in" to the rather skimpy default federal BK law exemptions.
This should give you the general lay of the land surrounding BK law.
