הראיה אצל השוכר, ואילו הערבות הבנקאית אצל המשכיר.

That is one of its basic meanings, but in sentences about people it often extends to with, in the possession of, or on the side of someone.

So in this sentence:

• הראיה אצל השוכר = the proof / evidentiary burden is with the tenant
• הערבות הבנקאית אצל המשכיר = the bank guarantee is with the landlord, in the landlord’s possession

So אצל is not always just physical location. It can also indicate who holds something or who it rests with.

Because Hebrew usually leaves out the verb to be in the present tense in sentences like this.

So:

• הראיה אצל השוכר literally looks like the proof with the tenant
• but it means the proof is with the tenant

This is completely normal Hebrew.

If you changed the tense, you would use a form of היה:

• Past: הראיה הייתה אצל השוכר
• Future: הראיה תהיה אצל השוכר

ואילו is a contrastive connector. Here it means something like:

• whereas
• while
• by contrast
• as for

It is stronger and more formal than a simple ו meaning and.

So the sentence sets up a clear contrast:

• one thing is with the tenant,
• whereas the other is with the landlord.

This is a very common point of confusion for English speakers.

Hebrew distinguishes the two sides clearly:

• שוכר = the person who rents something for themselves
  → tenant / renter
• משכיר = the person who rents something out to someone else
  → landlord / lessor

Related verbs:

• לשכור = to rent, hire
• להשכיר = to rent out, lease out

So Hebrew makes a distinction that English often leaves ambiguous.

Because the sentence is referring to specific, known parties and a specific, known guarantee.

In legal or contractual Hebrew, this is very common:

• השוכר = the tenant
• המשכיר = the landlord

Also, in Hebrew, if a noun is definite, its adjective must also be definite.

Compare:

• ערבות בנקאית = a bank guarantee
• הערבות הבנקאית = the bank guarantee

That is why both words have ה.

Because ערבות is a feminine singular noun, and Hebrew adjectives must agree with the noun in:

• gender
• number
• definiteness

So:

• ערבות = feminine singular
• therefore בנקאית = feminine singular adjective

Examples:

• מסמך בנקאי = a banking/bank document
• ערבות בנקאית = a bank guarantee
• ערבויות בנקאיות = bank guarantees

Not necessarily.

Hebrew ראיה can mean:

• a proof
• a piece of evidence
• in legal style, the proof obligation or evidentiary burden

In this sentence, הראיה is likely not talking about just one physical item. It sounds more like a legal expression meaning that the burden of proving something rests with the tenant.

So the singular form here is natural.

The word order is normal, especially in formal written Hebrew.

This is a balanced, verbless structure:

• הראיה אצל השוכר
• ואילו הערבות הבנקאית אצל המשכיר

Putting the noun first makes each clause sound neat and parallel. That is especially common in legal or formal styles.

You could move things around in other contexts, but the given order sounds polished and deliberate.

Yes. It sounds distinctly formal, and probably legal or contractual.

Especially formal are:

• הראיה אצל...
• the use of ואילו
• the parallel structure of the two clauses

In more everyday Hebrew, someone might say something more explicit, such as:

• השוכר צריך להוכיח את זה
• הערבות הבנקאית נמצאת אצל המשכיר

So the original sentence is natural, but it belongs more to legal or official written Hebrew than to casual conversation.
