If by ‘represent’ you mean in court or in a lawsuit, the answer is no.
A non-lawyer cannot represent a separate legal entity (in this case, a Trust) in any legal proceeding.
And an executed Power of Attorney document would have no bearing on this restriction.
To find a local attorney for FREE to represent the Trust in a court proceeding, visit Standard Legal’s Attorney Find page.
If you are named in a lawsuit or court matter in an individual capacity, then you can represent yourself; that is the very definition of pro se law.
To learn more about creating valid Trust and Power of Attorney legal forms, see Standard Legal’s document software titles.
