How can we
help?

UDF360 lets you open and edit the .udf documents used in UYAP on your phone and sign them with your mobile signature or e-signature card. For details, take a look at the product page.

There are two ways. You sign with your Turkcell, Vodafone or Türk Telekom mobile signature; all you need to do is approve the request that arrives on your phone. Or you sign with your e-signature card; this requires a card reader. To sign, your mobile signature must be active with your mobile operator. The terms for the account, verification and signature credits are explained in the answer below.

To sign, you must be at least 18 years old, sign in to your personal account, accept the current Terms of Use and complete your profile. Phone and email verification are mandatory; at your first signature, your identity details are matched with your signature certificate. Signing requires an internet connection.

1 signature credit = 1 signature. No credit is deducted for a signature that is not completed. When you start editing a document that comes from outside, however, 1 signature credit is deducted as a document ticket and covers one signature of that document; it is not given back even if you give up editing or the signature is not completed. While PRO is active, signature credits are not spent. Signature credits are not sold; they are granted as gifts. For eligible actions, you can get a single-use signature token, valid for 30 minutes, by watching an ad; this token is not added to your balance and does not accumulate. You can get at most 5 tokens per day through ads. PRO can be obtained with a monthly or yearly store subscription or as a gift.

When you verify your email address, 3 signature credits are given once. In the current campaign, every account that completes identity verification is PRO until the end of 30 November 2026 (Türkiye time); PRO starts at the moment identity verification is completed (at your first signature). Identity verification is not required for accounts opened before this text took effect or accounts that accepted the previous text of these terms; these accounts are also PRO until the same date. Of the accounts that complete identity verification, the first 100 get 6 months of PRO. The same person cannot receive this gift a second time. The gift PRO is not a paid subscription and does not renew automatically. For details of the campaigns and their current terms, read Terms of Use §3–6.

UDF360 does not access UYAP Avukat Portal automatically: you sign in to the portal yourself and you submit the document yourself. The app does not access your UYAP account; we do not ask for your UYAP username or password on our own screens.
