It's a complicated question.
My ExH and I were married for 16 years. He was so keen to re-marry, and I was so bogged-down as a Single Parent of four under 9 that I was behind on paperwork, we got divorced without a financial settlement. We still don't have one.
He and Wife #2 have now separated. How does their divorce affect me and my settlement, or can they not get a settlement till we have?
