How can an HR support an employee on probation period on his personal financial issue?

In general, an employee on probation in this circumstance should be treated in the same way as any other employee.  The main effect of probation is to give both parties the right to terminate the employment contract more quickly and easily than an established employee, but it is the hope and expectation of both parties that the employee should pass probation and become ordinary.

What actual help is available and appropriate depends on the circumstances and the company, and can vary from nothing to simply giving the employee some cash.  Salary advances and loans repaid by future salary deduction are common ways of helping.

By providing Salary advance and adjusting the same in subsequent months and even by providing support for any expenses needed for day to day business

By giving short-term employee loan.................

Thank you guys for your supportive answers.  Some Organizations have an emergency support policies in place while others don't.  

Here in Doha,  we don't only consider the probation itself but always the employment status of the worker.  Like the sponsorship, the government medical and of course the approval of the Gov't Ministries.  Considering all of these make it difficult for HR to decide on how much support we can give and the length of recovery if it is a loan.

One month advance salary and company residence for 15 days to 1 month should be enough to sustain a newbie for the initial few days. 

I agree with Duncan Robertson answer

 There are various ways of helping employee on probation through his/her financial.

# Few companies provides certain advance amount to new employee and that get settled in F&F if employee leaves the organisation.

# Few companies do provide some loan for short term.

# Few companies do provide salary in advance on request.

# Real help can be done if the initial expenses of hotel, travelling, shifting cost etc. can be directly borne by company instead of reimbursement.

Thanks for invitation

HR can support any employee specially those under probation. as regulated in HR / policy   an it will be vary from Company to other in general and best practice 

Support Employee Housing if He / She appointed from other country

or  Cash Money in Advance and this can be deducted from his monthly salary and it will be limited to Employee earning

he/she should be treated like permanent employee. short term loans of advance salary subjected to be deducted in three installments from his/her salary will surely serve him/her well.

The law should regulate that issue ( in every country) as it's a very sensitive mater which may lead to many employers to abuse that. Probation period- no notice, no need to worry then....

Try to give them paid time off.
