Ok, my mother in law owns a landscaping business. Everything was registered to her name. When her and her illegal husband were seperating she felt it was best to sell the business to her son and I so that we can take care of her (she has suffered multiple strokes and a case of dementia for which she has recovered from) my husband and I are buying the business in monthly installments throughout a period of time so that she has a steady income. Her drunken and abusive husband (who has no legal papers to be in the US) went behind her back and "sold" all of the customer names and contact info, along with thousands of dollars worth of equipment which was kept in a storage facility also in her name. Now it seems were in a power struggle to get the yards that legally belonged to us and the man her husband "sold" the names to is claiming to ber her business and causing us problrems and mass amounts of profit losses due to the "drama" that is going on. Can we sue them and what do we need to do so?
