LDoA redeeming

The question is:
I just got LDoA and wanna know if i can redeem it later since i currently do not
have eye of north expansion, in other words can i leave presearign and redeem it later, since i read something that kimmes the historian is the one that "places" it in HoM.?.

(read the guide but didnt not find anything about this)

Short answer: Yes.

Once you acquire the Eye of the North expansion, you may add titles to the HoM, including LDoA. EotN is required for adding titles to the Hall of Monuments.

Your titles will always exist as long as you keep the character with them--if you delete the character before the titles are recorded (either in the Hom or with the historian in pre-searing) then they will disappear.
Many times I have completed a title and forgotten to get to my HoM to record it--not a problem!!!

Thank you for a quick answer!

I agree to the above, just one thing to add.
You can put a title in the HoM on two places. In pre searing at the historian (if you have EoTN) or in the Hall of monuments. Though it won't be too difficult when you are level 20, if you leave pre you have to play through a part of the game till you reach the Hall of Monuments.
