This guide outlines how to retrieve signatures in a signed document.

### Finding all digital signatures

If you want to retrieve all the digital signatures in document, you can retrieve all the signed form fields in the following way:

### KOTLIN

```kotlin

override fun onDocumentLoaded(document: PdfDocument) {
    // This will return all signed signature form fields in the document.
    val signatureFormFields = document.documentSignatureInfo.signatureFormFields

    for (signatureFormField in signatureFormFields) {
        val signatureInfo = signatureFormField.signatureInfo
        // Process the signature information....
    }
}

```

### JAVA

```java

@Override
public void onDocumentLoaded(@NonNull PdfDocument document) {
    // This will return all signed signature form fields in the document.
    List<SignatureFormField> signatureFormFields = document.getDocumentSignatureInfo().getSignatureFormFields();

    for (SignatureFormField signatureFormField : signatureFormFields) {
        DigitalSignatureInfo signatureInfo = signatureFormField.getSignatureInfo();
        // Process the signature information....
    }
}

```

See [here](https://www.nutrient.io/guides/android/features/digital-signatures.md#how-to-create-digital-signatures) for information on how to create digital signatures.

### Finding all form fields with overlapping ink signatures

If you want to find signature form fields that aren’t digitally signed but that contain an ink signature, use the following snippet:

### KOTLIN

```kotlin

// This will return all form elements in the document.
document.formProvider.formElementsAsync
    // Convert them to an observable stream..flatMapObservable {
        Observable.fromIterable(it)
    }
    // Filter all signature form elements and cast them..filter { formElement -> formElement is SignatureFormElement }.cast(SignatureFormElement::class.java)
    // This will create a list of all form elements with a signature on them..flatMapMaybe({ signatureFormElement -> signatureFormElement.getOverlappingInkSignatureAsync().map({ inkAnnotation -> signatureFormElement }) }).toList().subscribeOn(Schedulers.io()).observeOn(AndroidSchedulers.mainThread()).subscribe({ formElements ->
        // A list of all form elements with ink signatures on them, or an empty list if there are none.
    }, { throwable ->
        // An error was thrown.
    })

```

### JAVA

```java

// This will return all form elements in the document.
document.getFormProvider().getFormElementsAsync()
    // Convert them to an observable stream..flatMapObservable(Observable::fromIterable)
    // Filter all signature form elements and cast them..filter(formElement -> formElement instanceof SignatureFormElement).cast(SignatureFormElement.class)
    // This will create a list of all form elements with a signature on them..flatMapMaybe(signatureFormElement -> signatureFormElement.getOverlappingInkSignatureAsync().map(inkAnnotation -> signatureFormElement)).toList().subscribeOn(Schedulers.io()).observeOn(AndroidSchedulers.mainThread()).subscribe(formElements -> {
        // A list of all form elements with ink signatures on them, or an empty list if there are none.
    }, throwable -> {
        // An error was thrown.
    });

```
