Limit the time that maintenance is paid to an ex-spouse after divorce – e.g. 10 years – rather than an on-going benefit for life. Make it retrospective. At present, the ex-spouse receives this until such times that they re-marry or die, regardless of whether they co-habit or earn sufficient to support themselves.
Why does this idea matter?
Pensioners ( state ) have to pass on some of their retirement pensions to their ex-spouses even though,at times, they re-married and,therefore,have two spouses to support.
