Here is what I always recommended; treat any Aviation Authority like they're Customs & Immigration in a Third World country run by a dictatorship.
Even with time building have your logbook signed and certified by the school. Not the friendly girl behind the front desk but the Chief Pilot or Chief Flight Instructor.
I, _______, Chief Pilot of __________ certify that the hours flown between (date)_____ and (date)___________ are true and correct.
___________
Signed & License number and school stamp.
Sacrifice half a page in your logbook to do this legibly.
In addition save all your receipts, for tax purposes later maybe and as evidence of hours flown.
Not the total bill but daily receipts that match up with the daily entries in your logbook.
If you file IFR you can print and save the online flight plans that list you as PIC.
Now in extreme cases and more for fun then anything else you can get a free Flight Aware account and save your flights.
So you have an audit by the logbook Nazi back in EASA-land and they question entries because your logbook looks like a drunk monkey got hold of a roller-pen. You now have all the evidence needed to prevent them from postponing your license issue.
