Minimum age to be in Relief Society/Elders Quorum Presidency?

I am a YSA ward clerk trying to put in a particular sister in LCR as a counselor in the Relief Society Presidency, as she was just called to that position. This sister is 19 years old, but it seems that LCR will not allow anyone under age 20 to be put into a Relief Society or Elders Quorum Presidency (I experimented with putting in a young man age 19 in the Elders Quorum Presidency, and LCR wouldn't allow me to). Is anyone else having this problem, or is it church policy that such presidency members must be at least 20 years old? Either way, will I just have to "hide" this calling in LCR for the time being?

I don't think there's an age requirement, but she does have to be part of that Relief Society before she can be added to that calling. Make sure she's really part of the ward and showing up in the appropriate RS rolls. If you've got more than one RS, that's probably the issue - she's a member of the wrong one.

I just tested to verify that you can have an 18-year-old Relief Society president.

You have one 19-year-old sister in your Laurel class. She isn't by chance the person you're trying to add as a counselor, is she?

You don't have any 19-year-old elders in your ward, so you won't be able to put any of them in the elders quorum presidency. The 19-year-old men you have in the ward not eligible because of their priesthood office.

Thanks, it turns out this sister was somehow in as a Laurel (and yes, the ONLY Laurel), and all I had to do was change her to Relief Society. Problem fixed
