What is the name of your state? Maryland...I am a little confused on child support laws, if anyone could help me. I have been divorced from my x for 1 1/2 years now. One day he just up and left for another woman. Got a divorce 5 months later (he admitted to adultery). I was left at home with our 6 year old to support. He has never paid me alimony or any sort of child support. In the divorce i did not go for child support...we make about the same amount of money and we share joint physical and legal custody. From what i understood child support wasn't an issue because of the amount of time our child spends with each of us or because we made approx. the same amount of money. Our child spends 4 nights with me and 3 with him a week. Since he walked out, his standard of living has grossly increased (owns 2 new automobiles, has purchased a home a year ago and is now building a bigger more expensive home (just for starters). I on the other hand have had my standard of living decreased. I had to sell our family home (he got 1/3 of the proceeds) and am now renting a small apartment. I would like to know how the child support works. Should i take him back to court? Will i get support even though we share our child 50/50? I am sure on paper his income is about the same (i do not know where all this money is coming from on his behalf). Any advice would be greatly appreciated.
