Egle..First, is your plant a Pachira? Good Luck/Money Plant?

Other than moving your plant, did you make any other changes?

The leaves that are yellow will not resume normal green color.
I'd remove dead foliage.

Setting a plant from low to bright sun can sunburns/mar leaves. Discolored leaves are dead.

With proper care, new growth should sprout.
When a plant is placed in a sunnier location, it needs to be done gradually.

Was your plant doing well in lower light?
Certain plants cannot tolerate bright/direct sun.

To be honest, I don't know the type of plant you have there. I think it's Pachira/Money Tree.

BTW, is the room/window hot? Growth slows/halts when temps exceed 90F and up. Which directions do/are old and new windows facing?

For the time being, remove dead foliage, place plant in a semi-cool, 65-75F area, in indirect light. See how it does. Keep soil semi-moist, not soggy. Let dry a bit between waterings.
Good luck, Toni

karalyte, from the angle of the leaf on the left, I'd say it is dying of old age or its attachment to the stem has been weakened or partly separated; the leaf on the right suffered some mechanical damage and if both were removed I suspect that the remaining leaves will be green and healthy.

I would check for bugs, spider mites specifically. How long have you had this plant?

Def. a money tree. They store water in their stumps/trunks and enjoy a nice lighted home. No direct sun. The leaves look to me like too much heat or light. Does not look like a watering problem. We keep these in our shop with little water maintenance.
