Legal Answers
10 Questions Answered
Q. In Illinois, an ex-spouse is hiding money by paying their new partner, who works for their business. Is this legal?
A: Is the "new partner" a business partner or a domestic partner? Assuming the question refers to a new domestic partner, the answer will depend on several factors, including whether the new partner is actually working for the business and whether the amount being paid to the new partner is what an employer would have to pay someone else to do similar work.
Q. If I have been married for 4 years and my husband is on the title and mortgage, is he entitled to half the house?
A: Based on the information you have provided, I am inclined to believe the house is your non-marital property, but that's not necessarily all there is to it. As much as I hate to answer a question with a question, I would also want to know whether he paid down the mortgage and whether he remodeled, upgraded, or improved the value of the property with his own money.
Q. 34-yrs married, $3M+ assets. Tell me more about "equitable" split. 50/50 is far from equitable all things considered.
A: The law does not require a 50/50 division. The court has the authority to divide marital assets and debts based on what is fair and equitable. The law lists several factors that the court may consider in making that determination, many of which you touched upon in your question.
