Il manque ta signature sur ce formulaire.

Yes, but not in the emotional sense of I miss you.

In Il manque ta signature sur ce formulaire, manquer means to be missing / to be absent / to be lacking.

That is different from sentences like Tu me manques, which literally work more like You are missing to me = I miss you.

So:

• Il manque ta signature. = Your signature is missing.
• Tu me manques. = I miss you.

French uses the same verb, but the structure and meaning depend on the context.

Here, il is an impersonal subject. It does not mean he.

French often uses il in a general, fixed pattern to introduce what is missing:

• Il manque un document.
• Il manque une date.
• Il manque ta signature.

This is similar to English using there in a sentence like There is a page missing. The il is just part of the structure.

So in this sentence, il does not refer to a person or thing.

Yes, that is grammatically possible, but Il manque ta signature sur ce formulaire is often more natural in this kind of practical or administrative context.

The version with il manque sounds like:

• pointing out an absence
• noting something required but not present
• making a neutral observation

Ta signature manque is understandable, but it is less typical in this situation.

So if you are talking about a form, document, or checklist, Il manque ta signature is a very natural choice.

Because signature is a feminine singular noun in French.

So the possessive adjective must match the noun:

• ta signature
• ma signature
• sa signature

Not:

• ton signature

A quick reminder:

• ton = masculine singular
• ta = feminine singular
• tes = plural

So ta signature means your signature because signature is feminine.

Because French usually uses a possessive adjective instead of an article in this kind of phrase.

So you say:

• ta signature
• ma signature
• sa signature

not:

• la ta signature

This works just like English:

• your signature
• my signature

The possessive already does the job, so no separate the-type article is needed.

Because formulaire is a masculine singular noun that starts with a consonant sound.

French demonstratives work like this:

• ce for masculine singular before a consonant
• cet for masculine singular before a vowel or mute h
• cette for feminine singular
• ces for plural

So:

• ce formulaire = this form
• cet email = this email
• cette signature = this signature
• ces formulaires = these forms

That is why ce formulaire is correct here.

For forms, documents, pages, and other physical or written surfaces, French often uses sur where English also often uses on.

So:

• sur ce formulaire = on this form
• sur la page = on the page
• sur le document = on the document

With a signature, sur is especially natural, because a signature is physically placed on the form.

Using dans would sound less natural here.

In this impersonal pattern, the verb often stays singular because the sentence begins with impersonal il:

• Il manque ta signature.
• Il manque deux signatures.
• Il manque plusieurs documents.

Even if the thing missing is plural, the verb can stay singular in this impersonal structure.

There is also a more personal version where the noun becomes the subject, and then the verb agrees:

• Deux signatures manquent.
• Plusieurs documents manquent.

So both patterns exist:

• Il manque + noun = impersonal, very common
• Noun + manque/manquent = more direct, with normal agreement

No, not in this sentence.

Here, manquer is used directly with the thing that is missing:

• Il manque ta signature.
• Il manque un tampon.
• Il manque une date.

The pattern manquer de exists, but it means something different: to lack a quality or thing in a more general sense.

For example:

• Ce texte manque de clarté. = This text lacks clarity.
• Il manque de patience. = He lacks patience.

So:

• Il manque ta signature = Your signature is missing.
• Ce formulaire manque de clarté = This form lacks clarity.

Those are two different uses.

It is neutral and very natural, especially in practical situations such as:

• forms
• applications
• official documents
• workplace communication

It is not especially formal, but it fits well in administrative language.

For example, a clerk, teacher, or coworker could say:

• Il manque ta signature sur ce formulaire.

If you wanted to sound more polite, especially with you in the formal sense, you would usually change ta to votre:

• Il manque votre signature sur ce formulaire.

So the structure is neutral; the level of formality mainly depends on the possessive you choose.
