It gets a little technical. It depends on where you are and for what value the shares settle. For example, if it is T + 3 then the trade only settles 3-days after the trade date. If it is T + 1 then it is the next day. Bonds usually trade T + 2, but equity can vary from market to market. So if you do not own the shares and you want to short them you have until settlement day to buy them in.
But then it is further complicated by failed trades. Those that do not settle in time. Theoretically, the counterpart to the trade can buy in those shares that fail, but again usually only after a grace period of say another 5-days. So you might be able to have a naked short on for up to 3-8 days in some cases without having to actually borrow those shares somewhere. That is just wrong. And it should be made explicitly illegal.
Stock borrowing is something else. That is like a reverse repo. You pay to borrow the stock, so that you can short it. In this respect you take something similar to temporary ownership of the share. I believe that is legitmate. The naked short is not.
Electronic dealing has in many cases made markets more democratic, but some of the rules are throw backs to when there were significantly fewer players that were actually members of a physical exchange. Then you knew who was good and who was a scoundrel. Global exchange trading electronically has blown those checks and controls out of the water. This is but one example.
$this->bbcode_second_pass_quote('', 'M')ore than $1.4 trillion of equities worldwide are now on loan, about a third higher than at the start of 2007, data compiled by Spitalfields Advisors, the London-based firm specializing in securities lending, show. Almost all of that is being used to speculate that shares will fall, according to James Angel, a finance professor at Georgetown University who studies short selling. The global economic slowdown, $447 billion in bank losses and an explosion of funds that can profit from stock declines spurred the increase in short selling, helping send 22 of 23 countries in the MSCI World Index into bear markets.

Never Have So Many Short Sellers Made So Much Money With Stocks$this->bbcode_second_pass_quote('', '[')u]The U.S. Securities and Exchange Commission last week limited so-called
naked short sales of Fannie Mae, Freddie Mac and brokerages. In such a strategy, speculators sell shares they haven't secured first. The decision comes amid an investigation of whether trading abuses contributed to the collapse of Bear Stearns Cos. in March.
