Q. A woman who counts Sefira and does not do melocho until she counts during the whole sefira until Shavuos. Recently she got married, and her husband only maintains the restrictions of sefira only until Lag Baomer. Does she now only maintain her minhag of not doing melocho only up to Lag Baomer?

A. Horav Shlomo Miller’s Shlit’a opinion is that it would depend on the reasons given to the custom of not doing work after sunset, until one counts sefira. (See question 1709 above).
If it is a result of the avelus for Rabi Akiva’s deceased disciples, once the period of avelus is over there is no reason to avoid work at that time, not so according to the other reasons mentioned.
As quoted above, few keep this tradition.
The Rov added, that whatever she decides to do, she should express that it is beli-neder, so she will not be bound to keep the custom by an oath, later on in her married life.
