Do bank statements in French need to be translated for a UK visa application? [duplicate]

The UKVI Visitor: supporting documents guide is clear on that point:

If you submit a document that is not in English or Welsh, it must be accompanied by a full translation that can be independently verified by the Home Office.

Among other documents, financial information is required:

Financial documents showing that you have sufficient funds available. These must clearly show that you have access to the funds, such as:

• bank statements
• building society book
• proof of earnings such as a letter from employer confirming employment details (start date of employment, salary, role, company contact details)
• where a third party (who is either in the UK or who will be legally in the UK at the time of your visit) is providing financial support to you e.g. a business, a friend or a relative, documents to show they have sufficient resources to support you in addition to themselves and any dependant family should be provided.

As your father supports you, his financial information/bank statements must be translated (and certified by a qualified translator/translation company). For the latter, the UK lists of translaters and interpreters abroad may help. Note it is not the sole source of such information, but just a place to start.

You may also want to show that you have access to his funds, and that they are set aside for your specific use. At this point, don't be tempted to have him transfer monies to your bank.
