Agree in principle with Truemanbrown. One major point you should consider when deciding whether to take of the legal entity or buying the assets /goodwill only without touching the legal entity are "potential liabilities" that might have accumulated against your husbands company. One of the major reasons to operate under a corporate umbrella is to benefit from the financial liability protection of a legal entity.
Yes. But there are many unknowns. In particular, but not limited to, what form of organization and tax structure is it, are you in a community property state or are there other things that impact title to the business and/or its assets, does the business require any special licensing that you do not have and can not obtain?
Also you have to ask, if you can, should you.
There are legal aspects of this question particularly pertaining to, but not limited to, liability and legislative compliance.
There are also tax, operational and financial planning aspects of the question. But again there are many unknowns including what is your exit strategy?
If you decide you should, it would be helpful to have a relationship with a CPA, an estate planning attorney, and possibly a financial advisor.
If you have had a family business, you should already have a relationship with a CPA. Entering and nearing retirement often also requires attorneys and financial advisors.
