Can a 18 year old girl can marry a 26 year old manWatch
If both love each other it should be fine
Conversely, the fact that you're having to ask this (for starters) has me questioning whether this is a very rational decision.
Yes, in the UK it is legal to marry at 18+ i think. Its perfectly fine to do this, but what is key is making sure you give advanced notice and stuff to both families and to make sure that both sets of parents are OK with this happening. Personally it seems a bit young but love never has an age limit, so main thing is just making sure that parents and relatives consent and agree with this, and yes it is legal. If you both love each other then thats perfectly ok, just bear in mind the age gap and the possible difference in mentality, feelings, emotions, wantings etc. Hope this helps 👍
