Mek5,
“to whom this is relevant should contact his local orthodox beis din and local orthodox Rav and not trust what unknown people say online”
Best comment!
I have read the comments, and no one even quoted any sources; everyone is just saying what they feel, think or think they saw/ heard etc. All I know, there are exceptions in all cases, and you cannot compare any case. There were cases were they did permit conversions, even for the sake of marriage (I’m not speaking about conservative/reform kind of cases or even liberal MO – I’m talking about true poskim prior to the times of Reform, like Rav Shlomo Kluger ZTL etc.), wherein of course, they accepted all mitzvos. It is basically up to the Bes Din to decide and, in ‘some’ cases there are exceptions.
If it is REALLY relevant l’Halacha, I can look it up, and post just the Marei makomos and you can represent it to your Rabbi – to ask a Posek (Note, this is not a decision that is up to your typical local Rabbi).
But again there has to be Kabalos Ol haMitzvos according to all. Thus, is a reason why all reform geyoris are null. Not only because they convert for marriage reasons.
(And yes, you can convert for marriage reasons and still accept mitzvos. E.g. Ivanka Trump did and is considered a proper conversion, at least after the deed has been done)
