How do I become the owner of my husband''s sole proprietorship?

You can become the owner of your husband's sole proprietorship by having him execute a bill of sale or other document of assignment that transfers the business to you. For certain kinds of assets that may be included in a proprietorship (such as real estate, patents or trademarks), other documents of legal transfer may also be required. As the new owner, you may change the name. You may not use your husband's EIN, which is personal to him. An attorney can assist you in the details of this transfer.
