text messages contract phone

[SNOWBall4girlz]

hi Just a quick question please regarding the use of text messages and the legality of them ?
Are they submissable in a tribunal from a contract phone?
just general texts proving that a person was having tea being picked up etc not in a murder case or anything like that

Thank you in advance

A text message can be submitted as evidence. However, it does not prove that the person sending the message was where they claim or doing what they say. The message could also be challenged on the basis that it was not sent by the owner of the handset.

They are all like buy me get me pick me up what time is tea and stuff more conversational.I am trying to prove that I was mainly responsible for my daughter over a period of time.
They are all from and to my mobile from another contract phone that belongs to my duaghter I can prove that they are saved from last year ?? have saved t- mobile dated texts as well to show the date and time are correct its not court but is in front of a judge at a tax credit tribunal.
Thank you for answering.

Not sure it really proves much tbh.
