Truth in making a match

Q: Is there a need to relate to a young man that the woman I am suggesting for him to date for the purpose of marriage takes anti-depressant pills? If there is an obligation, who should relate it?
A: This is the general principle: a severe matter must be related and if it is not, it is deception, but an unimportant matter need not be related. An unimportant matter is what is brought in the Gemara in Yevamot (45a): A person has a non-Jewish father and a Jewish mother, he is Jewish and there is therefore no obligation to tell. Depression is severe in that it can ruin a marriage. But it depends: if she takes pills and thus does not suffer from depression, there is thus no depression. What is the difference if there is no depression on account of a natural process or on account of the pills? If the current state is stable and there is no risk of a future deterioration, there is no need to tell. But if there is a risk that the pills will not work properly and depression will return – a risk greater than a regular person to whom this can also occur – then there is an obligation to reveal it. Who should reveal it – the woman or the matchmaker? It does not matter. They should work it out and the person for whom it is most comfortable should tell him.
