Question
How often should one check the tefillin and parshiot?
Answer
If worn every day, there is no need to check. It is also not advisable to give them to a random checker, as special craftsmanship is required to sew the tefillin back together. When purchasing tefillin from a skilled craftsman, part of the hiddur (enhancement) is that the craftsman knows how to sew them into a precise square, and various issues can arise from checking by someone who is not so expert.
