In my qdro it was stated a specific amount on the value date we chose. The qdro was signed off by everyone and my 35,000 had to sit for the next 10 years until he reached 55 I could take it out. Over the years I would request the value of the money what it was worth and the pension company would write me a letter stating the gains/losses. Well this past April I took a lump sum and had 20% taken off of 57,000. Well 6 months later the pension says they over paid me 27,000 and I only get the 35,000 and I need to pay the 27,000 back because it’s his . He (ex)found a error stating adjusting the gains and losses until the date of disbursement it said until date of valuation and had the pension plan come back and get my investment for the last 10 years because of the error in that one word. Now the pension wants it all back and I paid 11,000 in taxes on it. What can I do here? I don’t have the money and I didn’t wait 10 years for him to earn interest on my money
