The WTS has written instructions available only to elders. The info could be there and it is possible to get a download from some ex-jws of that publication. I do know that the elders are required to call at least once a year inactive jws (not attending meetings, not turning in time situation. The CO would come 2x a year to visit a congregation and would check the cards of inactive to see who the elders had visited during that year. But elders can do what my husband, once an elder was told, drive by the house and see if you can catch them smoking outside and having holiday decorations up! Several elders in some congregations, took out the inactive cards, as well as the df'd and da'd before the CO came. https://jws-library.one/?file=data/Books/Shepherd+the+Flock+of+God/202004/202004_sfl_E.html#bookmark743
Each year prior to the special talk and Memorial, a special effort should be made to contact all inactive ones living in the congregationās territory. If group overseers and their assistants need help, the service committee may ask other elders and qualified ministerial servants to work along with the group overseers. The brothers making such visits should be warm and upbuilding.
There is no formal arrangement to visit disfellowshipped or disassociated individuals each year. Rather, elders should use good judgment in determining whether and how to make brief contact with such ones. For example, if a disfellowshipped individual gives some evidence of changing his ways, an elder could provide him with a copy of the Return to Jehovah brochure and remind him of the steps he can take toward being reinstated. (Isa. 1:18; rj pp. 10-14) Such brief contact could be made while an elder engages in the house-to-house ministry. While shopping, an elder may see a disfellowshipped person who has not been contacted in years and choose to approach him. An elder may visit a dis-fellowshipped person at any time that is appropriate or even make contact by telephone.
