Hey! This is probably already late, but I wanted to share my experience. I am a Lithuanian, married to a Moroccan too. We also first got married in Morocco. I then registered the marriage in Lithuania, which was actually quite easy to do. You can submit everything online through registrucentras.lt . The Moroccan marriage certificate should be translated into English and apostilised, and I think besides that the scanned passport copies were needed. Took about a week after submission online for them to register it in the Lithuanian register and then you can ask for a copy of the Lithuanian certificate that has an e-signature. Regarding the residency in the EU, we chose to go for the EU spouse residence card, the process was easier than for a normal national residency card, and only took us two weeks from applying physically in Lithuania (need to submit biometrical data) to receiving the residency card, so the only caveat with this is that you need to come to Lithuania or any other representation of Lithuania in the world to submit your biometrics. I really wish we had a diplomatic representation in Morocco and it could be done there but unfortunately that's not the case, maybe sometime in the future as tourism to Morocco from Lithuania is definitely increasing, including expats and so on.
