He is gone on a trip and disappeared, or ran away from you without giving you divorce …
then according to some books, you have to wait till his age reaches 90 (so you know that he is probably dead) before your can remarry.
Is there an ijtehad on this ruling or its still the same?
Re: if your husband disappears, this is how long you have to wait..
I think she has to wait till few years ... if he appears then fine if not then she can marry someone else .....
kuch saalo k liye wait karna hota hay i guess not till he becomes 90 ...
Re: if your husband disappears, this is how long you have to wait..
I thought one had to wait for 7 yrs 
I don’t know why I thought that.
I also think that I read three years waiting period, but is that a confirmed fatwa
See this situation and associated fatwa is so relevant to the current situation of Pakistan, which made me think if we have the exact ruling in hand.
People in Pakistan disappear everyday. For how long, wife of Shahbaz Taseer has to wait? What about all those people that disappeared during Musharraf's time? For how long their wives should wait. Similar thing happened in Zia's time when people were going for Jihad, only to never come back.
Re: if your husband disappears, this is how long you have to wait..
4 years
hanafi position is borrowed from Malikis for lack of internal judgement
source: Muzaffar Shah Hussain
I think in this day and age, where world is so globally connected, and messages can be reached from one end to the other in the blink of an eye, even four years is quite a long period.
Just my two cents
Re: if your husband disappears, this is how long you have to wait..
my only concern is with welfare
I would think an exception or provision should be provided for extreme cases
a job for the Governor
I don't get it. What do you mean by the welfare? Welfare of the wife, you mean?
Re: if your husband disappears, this is how long you have to wait..
yeah, provision (food, and perhaps heating etc)
Re: if your husband disappears, this is how long you have to wait..
It might be possible for a woman to get khula in abstentia of husband ... in order to expedite marriage to someone else ... so long as the iddat period has lapsed - which assuming it has given the question ... but if the woman only wants to marry anew if she becomes widow and not divorcee then she will have to wait until confirmation of her husband's death or whatever duration until it is considered an absent time equivalent of him probably being dead.
Re: if your husband disappears, this is how long you have to wait..
I heard that too that it might be possible for a woman to get khula if husband is long gone, but I dont think that the ruling is universally accepted by all the Ulema. Majority is still on the side of making her wait till its sure that husband is dead.
Re: if your husband disappears, this is how long you have to wait..
Different position for different fiqhs, i remember reading about it, according to some its 2 years, other 4 years and if I can remember correctly, there is a saying of Ali r.a t=about some years and that it would be better if she can wait till he comes back or death is confirmed.
Re: if your husband disappears, this is how long you have to wait..
this is precisely why we need these teaching for women.

Re: if your husband disappears, this is how long you have to wait..
Relevant:
How long should the wives (and husbands) of the Muslims on Malaysian Airlines flight MH370 wait for.....
Re: if your husband disappears, this is how long you have to wait..
I don't think the iddat period would be relevant to this situation... Unless there is certain proof of his death, the woman would not be considered a widow.
I would assume she could file for khulla to seek the dissolution of her marriage on the ground of his disappearance through the Shariah court.
Re: if your husband disappears, this is how long you have to wait..
I think 4 years.
