High Court Family Division judge, Mr Justice Coleridge, has announced plans to set up a pro-marriage organisation.
The Marriage Foundation will aim to be a hub for information on marriage as well as commissioning research and eventually campaigning for "family-friendly" policies.
The Foundation is backed by family law specialists Baroness Deech, Baroness Butler-Sloss and Baroness Shackleton.
Mr Justice Coleridge said: "Over 40 years of working in the family justice system, I have seen the fallout from these broken relationships.
"There are an estimated 3.8million children currently caught up in the family justice system. I personally think that's a complete scandal."
He added: "My focus is on the children. I am unashamedly advocating marriage as the gold standard for couples where children are involved. I desperately want to avoid a moral crusade."
