alright this might have been asked a while back but i cant find it...
can a fallen paladin status be changed and if so how?

Uh, no. That's the whole point of being a palidin who has "fallen".

no what i mean is i read a while back that there might have been away to change alignment back say after doing the evil path on the nine hells. is there a way to change back to regular paladin and remain lawful good, i heard that it could be done i just wanna verify that it could be done

<font color="lawngreen" face="trebuchet MS"> IIRC SK can easily edit it the same way as getting rid of the alignment problem from hell... but in game there is no way back legitly AFAIK</font>

From what I've heard, Paladins and Rangers each get ONE chance to regain their status after they become Fallen, and that's by completing the quests that earn them their respective strongholds. Of course, if you became Fallen by failing a test in Hell, it's a little late to go after your Stronghold.

As far as becoming Evil is concerned, there's no legitimate way to change it back, as Glorfindel said. You can hack it back with Shadowkeeper, but that depends on which version of Shadowkeeper you have. (My version doesn't work with ToB :( )
