This is not a new topic, but it bears repeating.
Please don’t use the word ‘disclosure’ when the word ‘said’ or ‘alleged’ would do better.
AS v TH (False Allegations of Abuse)  EWHC 532 (Fam) (11 March 2016)
 … despite the fact that the use of the term ‘disclosure’ to describe a statement or allegation of abuse made by a child has been deprecated since the Cleveland Report due to it precluding the notion that the abuse might not have occurred (see para 12.34(1)), every professional who gave evidence in this case (except the Children’s Guardian) used the term ‘disclosure’ to describe what the children had said to them).
Disclose means to make known, to cause to appear, to allow to be seen. It has the connotation of truth. Whether you believe the allegation or not, until the Court has determined it, it is an allegation not a disclosure. I understand why social workers might feel uncomfortable about saying ‘alleged’ but ‘said’ or ‘told’ conveys perfectly well that the child SAID X, without giving a value judgment of ‘and X is true’
By way of concrete example, I can DISCLOSE to you that I think Natalie Portman is a fine looking woman. If, however, I tell you that I had a relationship with Natalie Portman and that she initiated it, you can’t properly say that I DISCLOSED that to you. That’s an allegation, not a disclosure. It might be true, it might not be. (It is not)
But if I tell you that, you’d be wrong to say I disclosed it to you. Stick with ‘said’
Example pulled out of thin air.
If you want to do one small thing to improve your written work, a find/replace on disclose / disclosure is a good start. Hint, if you are not using the word ‘disclosure’ in a Court document to mean ‘a bunch of documents provided by someone’ just find a replacement word. This is not just social workers, a random trawl on Bailii found me a dozen examples of the very best and brightest of our judiciary using it in judgments. Old habits die hard.
